Trial Summary

What is the purpose of this trial?

This trial tests a new treatment for certain cancers using a two-part method. The first part finds and attaches to cancer cells, and the second part delivers radiation to kill them. It aims to see if this treatment is safe and can be tolerated by patients with Small Cell Lung Cancer, Sarcoma, and Malignant Melanoma.

Will I have to stop taking my current medications?

The trial requires that you stop any systemic chemotherapy, radiotherapy, immunotherapy, or major surgery at least 3 weeks before starting the study treatment. It does not specify about other medications, so you should discuss your current medications with the trial team.

Is the GD2-SADA:177Lu-DOTA Complex safe for humans?

Research on a similar treatment, 177Lu-DOTATATE, shows it is generally safe for treating certain types of tumors, with most side effects being reversible. Common side effects include low white blood cell counts, but serious long-term effects like leukemia are rare. ^{1 2 3 4 5}

What makes the GD2-SADA:177Lu-DOTA Complex treatment unique for small cell lung cancer?

The GD2-SADA:177Lu-DOTA Complex is unique because it combines a targeting molecule (GD2-SADA) with a radioactive component (177Lu-DOTA) to specifically target and treat cancer cells, potentially offering a more precise treatment option compared to traditional chemotherapy. This approach is similar to other radionuclide therapies like 177Lu-DOTATATE, which have shown effectiveness in treating neuroendocrine tumors by targeting specific receptors on cancer cells. ^{1 3 6 7 8}

Findings from Research

The targeted alpha-particle therapy [225Ac]Ac-DOTA-TATE showed promising efficacy in delaying tumor growth in small animal models of lung neuroendocrine neoplasms, indicating its potential for treating patients who are resistant to standard therapies like [177Lu]Lu-DOTA-TATE.

In toxicity studies, [225Ac]Ac-DOTA-TATE demonstrated a high safety profile with no significant adverse effects in most animals, although higher doses led to chronic nephropathy, highlighting the need for careful dosing in clinical applications.

Salvage treatment with [177Lu-DOTA,Tyr3]octreotate is effective and safe for patients with progressive bronchial neuroendocrine tumors (NET) or gastroenteropancreatic NET (GEP-NET), showing a median overall survival of 80.8 months after initial treatment.

The treatment resulted in low rates of severe side effects, with only 6.6% and 7.7% of patients experiencing grade III/IV bone marrow toxicity after re-treatment and re-re-treatment, respectively, and no cases of severe kidney toxicity were reported.

The study successfully converted a gallium-68 imaging agent into a lutetium-177 therapeutic agent for prostate cancer, demonstrating strong PSMA binding affinity comparable to the FDA-approved [177Lu]Lu-PSMA-617.

Biodistribution studies in mice showed that the new agent [177Lu]Lu-7 had a longer blood half-life and higher tumor uptake than both [177Lu]Lu-4 and [177Lu]Lu-PSMA-617, indicating its potential for improved therapeutic efficacy.

[177Lu]Lu-DOTA-TATE shows promising antitumor activity in treating advanced somatostatin receptor-positive tumors, including pheochromocytoma/paraganglioma and bronchial neuroendocrine tumors, based on a systematic review of 16 studies.

The treatment is generally safe, with most side effects being mild to moderate and transient, similar to those observed in patients with gastroenteropancreatic neuroendocrine tumors.
